T6at the fiearing before the Board of County Commissioners was exlensive and complete, that all pertillent facts, matters and issues were subrnitted and that all interested pafties were heard at the hearing. Tlrat tlre application is in cornpliance with the Garfield Courty ZonirrgResolution of 1978, as amended.

RECOMMENDATION Staffis recotnmending APPROVAL, sulrject to the following conditions: (NOTE: Tlese conditions are moilellecl after the recent approval of the Rocky Morurtaiu Natural Gas/Public Service of colorado project in April of 1995). l. All proposals ofthe applicant shall be considered conditions of approval unless stated otherwise by the Board of Coturty Commissioners' Z. The applicant shall have 120 clays fi'orn the date of the Resolution of Conditional approval to meet all conclitions set forth in the Resolution. The Special Use Permit shallbe issue{ when all conclitions are met and shall expire 120 days after issuance, unless construction ol'tlse ltave commenced. 3. Standard procedures for the project will include implementation of erosion control antl revegetation measures to insure that lancls disnubed by construction activities will be restorerl to a stable, productive, and aestltetically acceptable condition. 4. Durirrg constructiorr of the project, a representative of Questar Pipeline Company shall: (a) act as a liaisol with the landowner/agency representative; (b) provide expertise to direct restoration of the right-of-way wlten special conditions are elcoturtererl, without causing construction delays; and (c) promote favorable public relations. 5. Installation ofthe pipeline will follow clearing of the construction area. Reclamation ?a- 6. and revegetation will follow the pipeline's ilstallation, especially in areas with soils that are highly susceptible to wind or water erosion' Questar Pipeline Company will conduct all activities associated with the project in a malllrer that will avoicl or minirnize degaclation of air, lald and water quality' In the colstlrction, operatiotr attd nraiutettatlce of the project, Questar will perform their activities accordi,g to afplicable air a,tl water quolity standarcls, related facility siting stanclarcls, and relatecl plans of irnplernentation' All desigtr, constructiol, operatiott, a1d maitttenance practices will be couducted accorclirig to safe and proven Errgineering Practices' When possible, project work will be coorclinated with other work occunirlg o11 of planned for locations alotlg the route' I l. construction- relatecl traffic will be restricted to routes approved by the controlling juriscliction. New access roacls oI cross-country vehicle travel will not be permitted unless prior approval was given by Garfield cou[ty.. Any ternporary roads used by euestar will be rehabilitated when construction activities are completed, as approved by Garfield CountY. 12. where possible, the right-of-way itself will be usecl as an access road during the cottstntction Period. 13.

All stream channels and washes will be retumed as near as practical to their natttral state' 15. All clarnaged County Roads shall be repairecl to the reqttirements of Garfield Cotutty Road and Bridge DePaftment' 16. To minirnize clisturbailce associated with installation of the pipeline, Questar will not glacle the riglrt-of-way outsicle of t|e trenclt line, except where necessary' o1 all level and gentlY sloPing tetrain. 17. Sidehill cuts will be kept to a minirnum to protect local resotlrces while providing a safe and stable plane for the efficient use of equipment' 18.
